Cercosporamide is a broad-spectrum natural antifungal compound, is actually a selective and highly potent fungal Pkc1 kinase inhibitor[1]. Cercosporamide, an antifungal agent that is recently shown to act as a unique Mnk inhibitor, exhibits antileukemic properties. Cercosporamide is a potent inhibitor of phosphorylation of eIF4E at Ser209 in AML cells and results in potent inhibitory effects on primitive leukemic progenitors (CFU-L) from AML patients. To determine whether Cercosporamide exhibits negative regulatory effects on cell proliferation and viability of leukemia cells, MTT assays are conducted. When U937 cells are incubated in the presence or absence of the increasing doses of Cercosporamide, a dose-dependent suppression of cell growth is found. Similar experiments with comparable results are seen when the effects of Cercosporamide on MM6 and K562 cells are examined[2].

Protocol
U937, MM6, and K562 cells are incubated for 5 days in the presence or absence of the indicated doses of Cercosporamide (1, 10, and 20μM) . Cell proliferation is assessed by an MTT assay[2].

Mice[2]
MV4-11 cells are implanted at a density of 5×106 cells per mouse. Tumors are measured by caliper and tumor volume is calculated. Once tumors reach a group mean of 100 mm3, animals are randomized to the following treatment groups: Ara-C (20 mg/kg daily dosed intraperitoneally), Cercosporamide (10 mg/kg twice daily, 20 mg/kg daily dosed orally by gavage), Ara-C plus Cercosporamide combinations (as above), or the relative vehicle controls (captisol for Cercosporamide and water for Ara-C)[2].
